Comet G3 ATLAS versus Starlink over Argentina

Comet G3 ATLAS versus Starlink over Argentina

Astrophotographer Eduardo Schaberger Poupeau: "On Monday, January 20th, I captured this image of comet C/2024 G3 ATLAS on the horizon, its nucleus now disintegrated after venturing too close to the Sun at perihelion. Yet, it left behind a spectacular tail, a luminous reminder of its fleeting visit. The scene is enriched by elements deeply rooted in our region: an old, weathered windmill missing some of its blades, serving as a perch for a "Carancho" (Caracara plancus - Southern Caracara), a characteristic bird of the central Argentine plains. To the left, as a nod to modern times, the streaks of a Starlink satellite train cross the sky, adding an unexpected contrast between nature and technology. This image bridges the ephemeral and the eternal, a reminder that even though the comet will soon disappear, its story will continue to shine. The photo was taken with a Canon R6 Mark II camera and a Sigma 105mm f/1.4 lens mounted on a fixed tripod without tracking."

C/2024 G3 ATLAS is a non-periodic comet. It reached perihelion (closest approach to the Sun) on January 13, 2025, at a distance of 0.09 AU (13 million km) from the Sun. It is potentially the brightest comet of 2025, with an apparent magnitude reaching −3.8 on the day of its perihelion. The comet is visible in the southern hemisphere before and after perihelion. It can only be observed in the daytime sky around perihelion in the northern hemisphere.

Comet C/2024 G3 was found by the automated Asteroid Terrestrial-impact Last Alert System (ATLAS) on April 5, 2024, in images obtained with a 0.5-m reflector telescope located in Río Hurtado, Chile. ATLAS is funded by NASA's planetary defense office, and developed and operated by the University of Hawaii's Institute for Astronomy.

Starlink is a satellite Internet constellation operated by Starlink Services, LLC, an international telecommunications provider that is a wholly owned subsidiary of the United States-based aerospace firm SpaceX, providing coverage to over 100 countries and territories.

Astronaut Nick Hague Takes High-Flying "Space-Selfie" | International Space Station

The NICER X-ray telescope is reflected on NASA astronaut and Expedition 72 Flight Engineer Nick Hague's spacesuit helmet visor in this high-flying "space-selfie." Also, visible in Hague's visor is the camera he is pointing toward himself to take this photograph. During a six-hour spacewalk, Hague patched several light leaks on NICER's 56 X-ray concentrators that block ultraviolet, infrared, and visible light while allowing X-rays to pass through to the mirrors underneath enabling the observation of neutron stars.

NASA astronauts Suni Williams and Nick Hague concluded their spacewalk at 2:01 p.m. EST on Thursday, January 16, 2025. It was the fourth spacewalk for Hague and the eighth for Williams, and it was the 273rd spacewalk in support of space station assembly, maintenance, and upgrades.

Williams and Hague completed their primary objectives, including removing and replacing a rate gyro assembly, installing patches to cover damaged areas of light filters on the Neutron star Interior Composition Explorer (NICER) x-ray telescope, and replacing a reflector device on one of the international docking adapters. The pair also checked access areas and connector tools that astronauts will use for future Alpha Magnetic Spectrometer maintenance.

Shenzhou-19 Crew Extends Spring Festival Wishes | China Space Station

Shenzhou-19 Crew Extends Spring Festival Wishes | China Space Station

As the Spring Festival approaches, China's Shenzhou-19 crew extended New Year wishes from space as they celebrated the completion of their mission's second series of extravehicular activities (EVAs).

The astronauts completed their second series of EVAs at 01:12 (Beijing Time) early Tuesday morning, January 21, 2025, according to the China Manned Space Agency (CMSA).

Over the course of 8.5 hours, astronauts Cai Xuzhe, Song Lingdong, and Wang Haoze worked closely together, with the support of the space station's robotic arm and a ground team, to complete multiple tasks, including the installation of protection devices against space debris, and an extravehicular inspection.

According to the agency, the astronauts have completed nearly half of their space mission, with a series of in-orbit scientific experiments and technological tests still to come.

In just a few days, the Shenzhou-19 crew will celebrate the Spring Festival amid their busy work aboard the space station.

Astronaut Cai Xuzhe began by thanking Shuguang (meaning "Dawn" in Mandarin), a cross-system, cross-departmental EVA support team, as well as all ground personnel. He also extended his New Year wishes to the entire nation from China's Tiangong space station.

"Every spacewalk is a new challenge. As long as we open the hatch, step out, and set to work, we will discover new horizons and achieve success. Now early in the morning, I want to express my gratitude to Shuguang and all the ground support teams. Thank you for your hard work. On behalf of the Shenzhou-19 crew, I also want to wish everyone a happy New Year and prosperity. May all your dreams come true," Cai said.

"With the Spring Festival approaching, I wish everyone and your families smooth sailing and good luck, and our country prosperity in the new year. Let's chase our dreams in the starry space and move forward together," Song said.

"Completing our mission in this festive season feels like a double celebration. I wish everyone the fulfillment of their dreams in the coming year and the start of a new journey as we continue to explore the universe," Wang remarked.

"Thank you, Shenzhou-19 crew, for your blessings, and we deeply appreciate your dedication. I also want to send my congratulations: Together, let's welcome a prosperous era, and hand in hand, we'll make our dreams come true. With you aboard the space station, the future is full of promise," Shuguang responded with gratitude and encouragement.

The Spring Festival, marking the start of the Chinese Lunar New Year, is the most important annual holiday in China, when people across the country return to their hometowns for Chinese Lunar New Year celebrations and family reunion.

This year, the festival falls on Jan 29.

The Eaton Fire ignited in the hills of Eaton Canyon, near Altadena, on the evening of January 7, 2025. By 10:30 a.m. the next day, the fire had quickly grown to cover more than 10,000 acres (40 square kilometers), according to Cal Fire. Around the time of the aerial image on January 11, 2025, provided here, the Eaton Fire had expanded to 14,117 acres (57 square kilometers), and the Los Angeles County Fire Department reported it was about 15 percent contained.

NASA’s Disasters Response Coordination System has been activated to support agencies responding to the fires, including the California Governor’s Office of Emergency Services. Response activities are centered on two primary requests from the local emergency managers: damage assessment information on built infrastructure, and impacts of air quality and human health risks.

Blue Origin's New Glenn Rocket Launch: Flight NG-1 Recap

Blue Origin's New Glenn Rocket Launch: Flight NG-1 Recap

Blue Origin's New Glenn rocket successfully lifted off at 2:03 a.m. Eastern Time (ET) from Launch Complex 36 at Cape Canaveral, Florida on January 16, 2025. It safely reached its intended orbit during today's NG-1 mission, accomplishing its primary objective.

About New Glenn

New Glenn stands more than 320 feet (98 meters) high and features a seven-meter payload fairing, enabling twice the volume of standard five-meter class commercial launch systems. Its reusable first stage aims for a minimum of 25 missions and will land on Jacklyn, a sea-based platform located several hundred miles downrange. Reusability is integral to radically reducing cost-per-launch.   

The vehicle is powered by seven of Blue Origin’s BE-4 engines, the most powerful liquefied natural gas (LNG)-fueled, oxygen-rich staged combustion engine ever flown. LNG is cleaner-burning and higher-performing than kerosene-based fuels, and the seven BE-4s generate over 3.8 million lbf of thrust. The vehicle’s second stage is powered by two BE-3Us, liquid oxygen (LOX)/liquid hydrogen (LH2) engines designed to together yield over 320,000 lbf of vacuum thrust.   

In addition to the BE-4 and BE-3U, Blue Origin manufactures BE-7 engines for our Blue Moon lunar landers and New Shepard’s BE-3PM engine.

3D Structure of Molecular Clouds in our Galaxy's Center | NASA Chandra

3D Structure of Molecular Clouds in our Galaxy's Center | NASA Chandra

This image represents a study using decades of data to learn about the 3D structure of molecular clouds in the center of the Milky Way. The panorama in this graphic contains radio data from the Submillimeter Array (green), and infrared from the European Space Agency's Herschel Space Telescope (red), and the Spitzer Space Telescope (blue). The inset shows the X-ray data from a molecular cloud from NASA’s Chandra X-ray Observatory. Billowy clouds, in shades of mostly red and blue, stretch across the middle of the image—wider than they are tall. Toward the right side of the image is a tiny, bright ball of light. This ball of light is Sagittarius A*, the supermassive black hole at the core of our galaxy.

Distance Estimate: About 26,000 light-years

Researchers have created the first 3D maps of molecular clouds, where stars form, in one of the most extreme environments in our Galaxy. They have studied previous flaring events from our Galaxy’s supermassive black hole, Sagittarius A* (Sgr A*). The center of the Milky Way Galaxy is an extreme environment where gas temperatures, densities, and turbulence are about ten times higher than the rest of the Galaxy. In this central region inflowing gas can sometimes find its way into the supermassive black hole at the very center. When Sgr A* feeds on this material it emits X-ray flares that propagate outwards in all directions. These flares interact with molecular clouds—gas clouds where stars form—in our Galaxy’s Center through the process of fluorescence. As the X-ray light travels, it illuminates slices of the molecular clouds over time, like an Xray scan.

The team developed a new X-ray tomography method to make 3D maps of two Galactic Center molecular clouds dubbed the “Stone” and the “Sticks” clouds. These maps are the first ever renderings of Galactic Center molecular clouds in three spatial dimensions. They used Chandra data spanning two decades to create their 3D models of the Stone and Sticks molecular clouds. While astronomers typically only see two spatial dimensions of objects in space, the X-ray tomography method allows us to measure the third dimension of the cloud because the X-rays illuminate individual slices of the cloud over time.

The researchers also used data from the Submillimeter Array and Herschel Space Observatory to compare the structures seen in the X-ray echoes to those seen in other wavelengths. Because X-ray data is not collected continuously, there are some structures seen in submillimeter wavelengths that are not seen in X-rays. However, these “missing” structures allowed the researchers to constrain the duration of the X-ray flare event illuminating the Stone Cloud. They determined that the X-ray flare couldn’t have been much longer than four to five months.

These results were presented by Danya Alboslani (University of Connecticut) at the 245th meeting of the American Astronomical Society meeting in National Harbor, MD. A paper describing these results is available:

Listen to The Sun! Transforming Heliophysics Data into Sound | NASA

Explore how data about the Sun from NASA's Parker Solar Probe, Magnetospheric Multiscale (MMS) and Wind spacecraft has been transformed into sound with NASA’s Coordinated Data Analysis Web (CDAWeb). Observe how audification can benefit heliophysics data analysis and uncover spectral features that the eyes overlook.

Heliophysics (from the prefix "helio", from Attic Greek hḗlios, meaning Sun, and the noun "physics": the science of matter and energy and their interactions) is the physics of the Sun and its connection with the Solar System. NASA defines heliophysics as "(1) the comprehensive new term for the science of the Sun—Solar System Connection, (2) the exploration, discovery, and understanding of Earth's space environment, and (3) the system science that unites all of the linked phenomena in the region of the cosmos influenced by a star like our Sun."

Extreme Supersonic Winds Raging on WASP-127b | ESO

Extreme Supersonic Winds Raging on WASP-127b | ESO

Astronomers have measured supersonic jet winds on WASP-127b, a giant gas planet located about 520 light-years from Earth. It is the fastest jetstream of its kind ever measured in the Universe with speeds up to 9 km per second. The team mapped the weather of WASP-127b using the CRIRES+ instrument on the European Southern Observatory’s Very Large Telescope (ESO’s VLT).

WASP-127 b orbits a G-type star. Its mass is 0.1647 Jupiters, it takes 4.2 days to complete one orbit of its star, and is 0.0484 AU from its star. Its discovery was announced in 2016.

The Boogeyman Nebula: LDN 1622 in Orion

The Boogeyman Nebula: LDN 1622 in Orion

The silhouette of an intriguing dark nebula inhabits this cosmic scene. Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region. In contrast, the brighter reflection nebula vdB 62 is more easily seen, just above and right of center. LDN 1622 lies near the plane of our Milky Way Galaxy, close on the sky to Barnard's Loop, a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion. 

With swept-back outlines, the obscuring dust of LDN 1622 is thought to lie at a similar distance, perhaps 1,500 light-years away. At that distance, this 1 degree wide field of view would span about 30 light-years. Young stars do lie hidden within the dark expanse and have been revealed in Spitzer Space telescope infrared images. Still, the foreboding visual appearance of LDN 1622 inspires its popular name, the Boogeyman Nebula.

Construction of The Extremely Large Telescope (ELT) in Chile: January 2025 | ESO

Construction of The Extremely Large Telescope (ELT) in Chile: January 2025 | ESO

The European Southern Observatory's Extremely Large Telescope (ELT) is a monumental project. Green light for the construction of the largest optical telescope on Earth started in 2006. As this image, taken in early January 2025 shows, the telescope is nearing its completion, step-by-step. 

The Extremely Large Telescope (ELT) has been appropriately dubbed the "Colosseum of Atacama". This mega-structure is seen in this picture under construction as of early 2025. The evening's sunlight traverses the ELT's dome, illuminating the altitude structure. This 50-meter-tall feat of engineering will carry all 5 mirrors of the ELT, including the giant M1 mirror on its base. The semicircular plate in the image is part of a hydrostatic frame that supports the altitude structure. It is perforated to allow air to flow from the mirror to the ambient air, preventing temperature differences. The ELT is not only a true Colosseum, but everything has been designed in extreme detail. 

This drone shot, dating from early January 2025, peers right into the dome of the Extremely Large Telescope (ELT). The dome is not yet fully covered in this image. Once finished, the ELT will be the world's biggest eye on the sky, thanks to its 39 meter diameter main mirror. It will be supported by the polygon structure inside the dome. The 'spider' on top of it will hold the telescope's secondary mirror at its center.

This image shows the inner frame of the Extremely Large Telescope (ELT), the main structure of the telescope. It will contain all five mirrors of the ELT. Taken in January 2025, the skeleton is completed but still needs to receive all the segments that make up the main 39-meter mirror, set on its honey-comb-shaped base and the other, smaller mirrors. It will be set inside the central tower. Once completed, the ELT will be a leading optical-to-infrared telescope.

The evening sun bathes the construction site of the Extremely Large Telescope (ELT) in red light. This drone image, taken early January 2025, reveals the metal altitude structure inside the dome. It is 50 meters high and will carry the ELT's five mirrors. It rotates so that it can be pointed at different parts of the sky. The 'spider' on top will hold the telescope's secondary mirror, the perforated structure below carries the main mirror, and the central tower supports the ELT's remaining three mirrors.

The European Southern Observatory's Extremely Large Telescope (ELT) is truly a massive building. These images show the construction stage of the ELT's dome and main structure on January 8, 2025. Despite their massive size, these structures are able to rotate and tilt the mirrors to the targeted observation with great precision. The ELT is almost as tall as London's Big Ben clock tower and larger than Rome's Colosseum. The construction materials used for the ELT include: 10,000 tonnes of steel, 30 million bolts or 500 km of cables. Even compared to other large telescopes, the ELT is a one-of-a-kind.

The ELT can be seen including its dome, central structure, and base of the M1 mirror. The ELT stands at Cerro Armazones in Chile's Atacama Desert and will be one of the main flagships of the European Southern Observatory (ESO) for the next two decades. 

Altitude: 3,046 meters

Planned year of technical first light: 2027

Shenzhou-19 Crew Completes Second Spacewalk | China Space Station

Shenzhou-19 Crew Completes Second Spacewalk | China Space Station

Members of the Shenzhou-19 crew aboard China's orbiting space station completed their mission's second series of extravehicular activities (EVAs) at 1:12 a.m. (Beijing Time) on Tuesday, January 21, 2025, according to the China Manned Space Agency (CMSA).

Shenzhou-19 astronauts arrived at the Tiangong Space Station in late October 2024.

In their first EVAs on December 17, 2024, Cai Xuzhe and Song Lingdong set a new world record for the longest single spacewalk, spending nine hours outside the Tiangong space station. They worked on several tasks including the installation of protection devices against space debris. This feat exceeded the previous spacewalk record set by two American astronauts two decades ago.

Planet Saturn with Moons Tethys, Mimas, & Janus | NASA Cassini Mission

Planet Saturn with Moons Tethys, Mimas, & Janus | NASA Cassini Mission

Image of planet Saturn with moons Tethys, Mimas, and Janus captured by NASA's Cassini spacecraft on March 13, 2006.

Tethys is Saturn’s fifth largest moon. Its irregular shape is 331 miles (533 kilometers) in mean radius, with dimensions 669 x 657 x 654 miles (1076.8 x 1057.4 x 1052.6 kilometers). This cold, airless and heavily scarred body is very similar to sister moons Dione and Rhea except that Tethys is not as heavily cratered as the other two. This may be because its proximity to Saturn causes more tidal warming, and that warming kept Tethys partially molten longer, erasing or dulling more of the early terrain.

Tethys’ density is 0.97 times that of liquid water. This suggests that Tethys is composed almost entirely of water ice plus a small amount of rock.

Less than 123 miles (198 kilometers) in mean radius, crater-covered Mimas is the smallest and innermost of Saturn’s major moons. It is not quite large enough to hold a round shape, so it is somewhat ovoid with dimensions of 129 x 122 x 119 miles (207 x 197 x 191 kilometers, respectively). Its low density suggests that it consists almost entirely of water ice. It is the only substance detected on Mimas.

At a mean distance just over 115,000 miles (186,000 kilometers) from the massive planet, Mimas takes only 22 hours and 36 minutes to complete an orbit. Mimas is tidally locked: it keeps the same face toward Saturn as it flies around the planet, just as our Moon does with Earth.

Janus is an inner satellite of Saturn. It is also known as Saturn X. It is named after the mythological Roman god, Janus. This natural satellite was first identified by French astronomer Audouin Dollfus on December 15, 1966, although it had been unknowingly photographed earlier by French optical engineer, Jean Texereau. 

NASA's Cassini spacecraft arrived in the Saturn system in 2004 and ended its mission in 2017 by deliberately plunging into Saturn's atmosphere. This method was chosen because it is necessary to ensure protection and prevent biological contamination to any of the moons of Saturn thought to offer potential habitability.

The Cassini-Huygens mission was a cooperative project of NASA, European Space Agency (ESA) and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the mission for NASA's Science Mission Directorate, Washington. JPL designed, developed and assembled the Cassini orbiter. The Cassini radar instrument was built by JPL and the Italian Space Agency, working with team members from the U.S. and several European countries.

Shenzhou-19 Astronauts Gear Up for Second Spacewalk | China Space Station

Shenzhou-19 Astronauts Gear Up for Second Spacewalk | China Space Station

China's Shenzhou-19 crew, currently aboard the Tiangong Space Station, is ramping up preparations for their second extravehicular activities (EVAs) set to take place within the coming days.

According to the China Manned Space Agency (CMSA), the three astronauts are in good health, and the space station is operating smoothly, creating optimal conditions for the upcoming spacewalk.

In a video released on Monday, January 20, 2025, the crew was seen making final preparations ahead of the mission. They have conducted thorough checks of their spacesuits and practiced mechanical arm operations in orbit. Two crew members assigned with spacewalk have been rehearsing their tasks in their spacesuits inside the space station.

The trio has also carried out a full-process simulation and reviewed contingency plans in preparation for the EVAs.

Shenzhou-19 astronauts arrived at Tiangong in late October 2024.

In their first EVAs on December 17, 2024, Cai Xuzhe and Song Lingdong set a new world record for the longest single spacewalk, spending nine hours outside the Tiangong space station. They worked on several tasks including the installation of protection devices against space debris. This feat beat the previous spacewalk record set by two American astronauts two decades ago.

Since their first spacewalk, the crew has undertaken a series of tasks, including inspections and maintenance of the space station's equipment, system-wide pressure emergency drills, and preparations for the second EVAs. In addition the CMSA noted that they made steady progress in experiments in fields such as space material science, space life sciences, and aerospace medicine.

The Tarantula Nebula's Outskirts in The Large Magellanic Cloud | Hubble

The Tarantula Nebula's Outskirts in The Large Magellanic Cloud | Hubble

This NASA/European Space Agency Hubble Space Telescope picture features a dusty yet sparkling scene from one of the Milky Way’s satellite galaxies, the Large Magellanic Cloud. The Large Magellanic Cloud is a dwarf galaxy situated about 160,000 light-years away in the constellations Dorado and Mensa. 

Despite being only 10–20% as massive as the Milky Way galaxy, the Large Magellanic Cloud contains some of the most impressive star-forming regions in the nearby Universe. The scene pictured here is on the outskirts of the Tarantula Nebula, the largest and most productive star-forming region in the local Universe. At its center, the Tarantula Nebula hosts the most massive stars known, which weigh in at roughly 200 times the mass of the Sun.

The section of the nebula shown here features serene blue gas, brownish-orange dust patches and a sprinkling of multicolored stars. The stars within and behind the dust clouds appear redder than those that are not obscured by dust. Dust absorbs and scatters blue light more than red light, allowing more of the red light to reach our telescopes and making the stars appear redder than they are. This image incorporates ultraviolet and infrared light as well as visible light. Using Hubble observations of dusty nebulae in the Large Magellanic Cloud and other galaxies, researchers will study these distant dust grains, helping to understand the role that cosmic dust plays in the formation of new stars and planets.

Image Description: A section of a nebula, made up of layers of colored clouds of gas of varying thickness. In the background are bluish, translucent and wispy clouds; on top of these are stretches of redder and darker, clumpy dust, mostly along the bottom and right. In the bottom left corner are dense bars of dust that block light and appear black. Small stars are scattered across the nebula.
